Take the multiples of 72.
12 = 12 x 6. Again split 12 and 6.
12 = 4 x 3 , 6 = 2x3
Square root of 12 = (square root of 4 x square root of 3 ) * (square root of 2 x square root of 3)
= (square root of 2 x square root of 2) x (square root of 3) * (square root of 2 x square root of 3)
= 2 x 3 x square root of 2
= 6 x square root of 2
